When first programmed the Teensy will automatically have the Compile/Date time. If you wish to get that date/time on subsequent powering of the Teensy you can use the code below: Serial.print("Compile: Date "); Serial.print(__DATE__)...

I would be interested to know how it all works out. Another titbit, if you are sending to sleep and waking it up via Teensy, it takes the EST32C3 something like 50ms to become compos mentis.

Just an addition, if you are intending using the ESP32C3 from battery, the TenStar has an LED always on. I suppose it could be cut/clipped off.

I think I tried that and NO it won't. I tried all sorts of action on the PC and they all resorted in Teensy ignoring the file. It's interesting that when the file is opened a file is returned but Teensy then does not carry out any actions on the...

I have a system where I gather data and write it to a file every minute. If I cut the file (from Teensy) and paste elsewhere on the PC the Teensy will not re-create the file and write to it. dataFile = SD.open("datalogZ.csv", FILE_WRITE); is...

Whilst you are developing your project (software wise) I suggest that you use an ESP32C3 board with a connector. It makes programming and re,re,re programming so much easier, just having to plug in the ESP32C3 rather than un plug it from the PCB...

Yes, those 8 pins only take up a small amount of space, the rest of the T-01C3 could just overhang the end. The other thing you could do is mount the Teensy to the top of the PCB with the ESP32C3 mounted from below with a slight (say 0.2") offset...

Here, on the left, is another cheap, small ESP32C3.

Which one the little one on the left or the one on the bottom right which has a USB C connector. The one on the left has 2 rows of 4 pins.

Just had a look at the WizFi360 and I am pretty sure it's an ESP32.

I think £32.50 for the board (brand new unopened). Carriage I will look into, but looks to be less than £10, it depends what size and weight I can get it down to. Just throwing it in an envelope would be £2.50 but I am not sure about how secure...

I use ESP32C3s connected via Rx/Tx - 500000 bps is hast enough for me and easy to debug - send as text until sorted, then change to send binary data. Below is a picture of the system I use, I acknowledge that it is probably much larger than you...

I have some T3.5's if you are interested. Where are you? Given that you are looking at 1275cc A Series it could well be in the UK...Oh perhaps not given the time of day of your post.

No.

I am very interested in one of those. I too have age related hearing problems.

I don't know if this is of any use. Code from the above link, modified for Teensy, might need some more. #include <SPI.h> uint32_t startTime, elapsedTime, old_res; #define SCALE_FACTOR 0.000152587890625 /* D14 and D15 should be grounded if you...

I have had a similar problem to yourself, receiving temperature and humidity readings from multiple ESP32Cs by a single ESP32C and transmitting to Teensy 4.1 via UART for storage for future analysis. At first I used Text transmission, like...

Here is a list of the Libraries in Teensyduino: Obviously you are not limited to these libraries, many more general libraries can be used. AccelStepper Adafruit_NeoPixel Adafruit_nRF8001 Adafruit_STMPE610 Adafruit_VS1053 ADC AltSoftSerial Artnet...

Effectively you will be using the Teensyduino libs if you are using a Teensy. A lot of people use PlatformIO with Teensy but it is NOT a PJRC supported platform. Paul does a lot to help those people using PlatformIO with their problems but it is...

I would suggest using Teensyduino and the Arduino IDE so that all the libraries become available to you. Use VisualMicro and VisualStudio if you don't like the look and feel of the Arduino IDE.

If you break the connection and then put a Schottky diode across them you get the best of both worlds without having to re-solder.

Hi all, yes it's been a little bit. So I guess I lost my Teensy 4's, lol, so I'l order a 4 and 4.1 soon.

Let's start with the first serial port on pins 1&2, this is addressed as Serial1, so Serial1.begin(11520); works. Likewise for the second serial port on pins 7&8, this is addressed as Serial2 and Serial2.begin(11520); works. I am sure you get the...

The SDA lines may need to have pull up resistors added.

Could you explain what you mean by the above sentence. I think I know what you mean, but we have a large number of members who DO NOT have English as a first language and may not understand your sentence, especially the halts the Teensy inviting...

Hi, @duff it's so good to see you back.

I have some in the UK, if you are interested.

This should have the 9bit information you require.

Ditto on Windows 10.

Can't you buy the chips from Mouser then ship them to the PCB factory yourself?

Personally I would use OLED screens such as this. Square ones are available a little cheaper. They are driven by I2C which is slower than SPI, but I suspect that speed is not a priority as they will (I guess) not be changed very frequently...
